Data storage system having associated situational analysis framework for automatic response to movement in a state space

摘要

The operation of a data storage system is controlled by determining dimensions of a situational state space characterizing operating conditions of the data storage system, associating policy sets with respective states of the state space, monitoring system operation in the state space, selecting a particular one of the policy sets based on an identified current state in the state space, and controlling the operation of the system in accordance with the selected policy set. These operations are performed by a processing device incorporated in or otherwise associated with the system, with the processing device implementing a situational analysis framework comprising a learning module coupled to a production module. The situational analysis framework may be part of a policy engine. The dimensions of the situational state space in an illustrative embodiment may comprise two or more dimensions selected from one or more dimension categories such as load, performance, time and event state.
